Title:
METHOD FOR TRANSMITTING AND RECEIVING SRS, AND COMMUNICATION APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/098712
Kind Code:
A1
Abstract:
A method for transmitting a sounding reference signal (SRS) by a terminal comprises the steps of: receiving, from a base station, the number of SRS repetition symbols, group hopping patterns, sequence hopping patterns, pattern selection information, and hopping selection information; generating an SRS sequence by applying a group hopping pattern and a sequence hopping pattern selected according to the pattern selection information and the hopping selection information; and transmitting the SRS on the basis of the SRS sequence, wherein the group hopping patterns include a group hopping pattern calculated using the number of SRS repetition symbols, the sequence hopping patterns include a sequence hopping pattern calculated using the number of SRS repetition symbols, and the hopping selection information selects whether to activate group hopping and sequence hopping.
